1be175f929 vc1dec: Handle top and bottom blocks in vc1_mc_4mv_chroma4() differently if needed 
Now it can use different references for those blocks and even use
averaging.

This fixes several chroma artifacts in several videos.

28243b0d35 vc1dec: Redesign the intensity compensation

Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following

93b1281264 vc1dec: Shuffle field MVs after decoding, not before 
This simplifies the code since copying MVs to the reference is not needed

Also remove the unused mv_f_last.

Fixes a small number of artifacts in black_screen_VC-1.mkv
and several more artifacts in other videos.

9b6f47c448 matroskadec: export full wavpack blocks. 
This allows us to get rid of demuxer-specific hacks in the decoder and

2768f7e4fe sparc: VIS mnemonics 
Currently, if VIS is enabled by configure, it will also be enabled at
run-time regardless of its support in the hardware. Thus, masking VIS
usage as it is done in vis.h by constructing binary instructions is
pointless. Using normal VIS mnemonics in inline assembly allows to take
advantage of automatic register allocation, gets rid of register
variables, which are unsupported by suncc for SPARC, and improves code
readability.

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid 
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.

94235f2ba2 indeo3: avoid writes without necessary alignment in copy_cell() 
Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

015821229f vp3: Use full transpose for all IDCTs 
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.
